Answer:
$9.10.
Step-by-step explanation:
We are told that Hailey paid $13 for [tex]1\frac{3}{7}[/tex] kg of sliced salami.
To find the cost of per kilogram of salami we will divide 13 by [tex]1\frac{3}{7}[/tex]
First of all we will convert our mixed fraction into improper fraction.
[tex]1\frac{3}{7}=\frac{10}{7}[/tex]
[tex]\text{The cost of per kg of salami}=13\div{\frac{10}{7}[/tex]
Dividing a number by a fraction is same as multiplying the number by the reciprocal of fraction.
[tex]\text{The cost of per kg of salami}=13*{\frac{7}{10}[/tex]
[tex]\text{The cost of per kg of salami}=\frac{91}{10}[/tex]
[tex]\text{The cost of per kg of salami}=9.1[/tex]
Therefore, the cost of per kg of salami was $9.10.
